I’ve been using a 1 wire network for quite some time now, but when I deleted a directory to much on my server, I lost a lot of the stats that I had gathered. A couple of weeks ago I finally got my behind in gear again and rebuild my network, this time making sure it all gets backed up ;)

One day I’ll write something about how it’s all been done, but for now you’ll have to suffice with some pretty graphs.

Here’s the daily graph for the temperatures in our bedrooms for the past 24 hours:

And recently I added a Current Cost meter to my network, which gives me the shocking facts about my electricity usage for the past 24 hours:

The above graphs are updated hourly, and I’ve got other graphs too, extending the period of graphing. You can find them here for the time being.

I’ve never been sure how accurate (in absolute terms) the 1-wire sensors are. I’m wondering, if you physically swapped the Senna, Bedroom, and Justin sensors, would you STILL have the consistent temperature difference between the three locations in the same order?

I have my CC twittering my consumption in kWh at the end of each 24 hours, and once i can figure out my tariff it’ll show me what it’s cost me each day. Scary!
I pull the daily consumption from sql with the following query in a shell script:
